Camera compatibility

Camera models that the flash can work with. Note that this parameter is usually indicated in the characteristics very approximately — only camera manufacturers are named, but there is no talk of models as such. Therefore, before purchasing a flash, it makes sense to separately clarify whether it will work normally with your camera — for example, on the manufacturer's website or thematic forums. This is especially true for devices from third-party manufacturers — for such models, the likelihood of problems is somewhat higher than for “native” flash cameras. At the same time, devices from the same company usually have the same requirements for connecting flashes, and therefore this parameter is with a fairly high degree of accuracy allows you to evaluate compatibility.

If the specifications of the flash indicate compatibility with several brands of cameras, this usually means that this model is available in several variations, each of which is designed for a different manufacturer.

It is worth noting that the "non-native" camera and flash may be quite compatible and work fine in most shooting modes. Nevertheless, support for TTL (see below) and a number of other specific functions in this case is usually out of the question, and in general, the reliability and efficiency of this combination is lower than that of a camera with a "native" flash. Therefore, it is better to choose all the same accessories with directly claimed compatibility.

Of t...he compatible cameras currently in use: Canon, Fuji, Leica, Nikon, Olympus, Panasonic, Pentax, Samsung, Sigma, Sony.

Reload time

The time it takes the flash or generator (for studio flashes) to prepare for the next flash. The smaller it is, the better. This parameter is especially important for continuous shooting, when the interval between frames is small: if you often shoot in this mode, you should look for a flash with the shortest possible recycle time. Also note that the characteristics usually indicate the shortest recharge time; in some operating modes, it may be significantly more than stated.

Number of impulses

The number of flashes that the flash can fire without recharging the battery or changing batteries (see "Power"). This parameter is very approximate, because. in fact, it strongly depends on a number of factors: pulse duration, use of the display and its backlight (if any, see below), autofocus backlight (see "Features"), etc., and with replaceable batteries — even and on their quality. Often, manufacturers indicate in the characteristics the “perfect”, the maximum possible number of pulses — i.e. with their minimum duration, non-use of additional functions and even the optimal temperature regime for the battery. In reality, this figure may be lower. Nevertheless, the data indicated in the characteristics makes it quite possible to evaluate the battery life of the flash and even compare different models with each other.

Pulse duration

The duration of the pulse of light provided by the flash. This indicator can range from thousandths to hundred thousandths of a second; it is usually expressed as a fractional number with a unit in the numerator, such as 1/880 s. The human eye does not notice the difference, but in some shooting modes it can become critical. For example, to capture fast-moving scenes (such as splashing water, the flight of an insect, or the movement of machine parts) you need to choose a flash with the shortest flash duration possible — otherwise the image may be blurry.

The longest pulse duration in modern photoflashes is about 1/800 s; the minimum value can reach 1/30,000 s or even less.

Features

Autofocus assist light. The presence of an auxiliary illumination function in the flash for the camera's autofocus system. Modern cameras in the vast majority use the so-called passive autofocus systems, which have one serious drawback: very low efficiency in low light and/or low contrast of the subject being photographed. Autofocus assist light is designed to solve this problem: before focusing, the scene is illuminated by a separate lamp, located, in this case, directly in the flash body. This ensures a sufficient amount of light for normal autofocus operation. Most often, the backlight lamps give off light of a characteristic reddish hue, but some advanced models use infrared illumination - invisible to the eye, but perceived by the camera. In addition, backlight systems can use a special light pattern instead of a solid beam, which further simplifies the task of autofocus systems. In any case, the presence of this function is especially important given that the flash is often used as a light source in low light.

— On-camera control. The ability to change the flash settings using the controls of the camera to which it is connected. In some cases (for example, with a wireless connection), this is much more convenient than switching attention from the camera to the flash.

Automatic zoom. The ability to automatically change the flash light scattering angle. For the scattering angle..., see the corresponding point above, but here we note that this function provides synchronization between the flash and the lens: when the focal length of the lens changes, the scattering angle automatically changes. This ensures the most effective illumination of the scene and at the same time saves you from having to manually readjust the flash each time to the changed viewing angle.

Manual zoom. The ability to change the flash spread angle (see "Light spread angle") manually. This function expands the possibilities for "fine" adjustment of operating parameters and allows you to set parameters that are not available with automatic zoom (see above). In addition, it will be useful if you have to use several fixed lenses with different focal lengths - the flash can be easily adjusted for each of them.

Operation in master mode. The ability to operate the flash as a master for a system of several flashes. The entire system is controlled via the master flash, the parameters of the slave flashes are set, and the command to fire is given (note that the master flash itself may not give a pulse at all). If you plan to shoot using a system of several flashes, you will definitely need a model with this function — without it, creating a system is impossible. Of course, the master and slave flashes must be mutually compatible; this point should be clarified separately.

Slave mode. The ability to operate the flash as a slave in a system of several flashes. In this mode, the device is connected to the master flash and is triggered by a command from it. For more information on flash systems, see "Master mode operation" above.

— Radio synchronizer. A device designed for wireless control of a flash or a set of flashes (if each of them has its own receiver). Usually it is a separate module installed in a hot shoe; upon a command to trigger, this module sends a radio signal to all receivers tuned to it, ensuring synchronous triggering of the flashes. At the same time, some models of lamps with this function are capable of receiving via radio not only the trigger signal, but also the operating parameters (primarily the duration and power of the pulse).

Wireless control

The ability to wirelessly connect the flash to the camera or to another flash as a master/slave (if such functions are available, see below). The format and specific features of such a connection may vary: wired connection, IR channel, radio, etc. Wireless control is indispensable if the flash needs to be placed away from the camera; it also facilitates the creation of systems from several flashes for organizing optimal lighting. These capabilities are especially useful for studio shooting (although this is not the only thing).
